IMPFiOVEMENT IN VEGETABLE GRATERS AND CUTTERS.

Specification forming part of Letters Patent No. 220,723, dated October21, 1879; application filed Au gust 11, 1879.

To all whom it may concern.-

Be it known that I, WILLIAM MILD, of Hamilton, in the county of Butlerand State of Ohio, have invented certain new and useful Improvements inVegetable Graters and Cutters, of which thefollowing is a specification.

My invention relates to that class of machines known as vegetablegrat'ers and out ters, and has for its object the construction of thevegetable-grater in such a manner that the grater-cylinder can beremoved from the machine for cleaning, or laid away to prevent corrosionwhen the machine is out of use.

In all other machines for this purpose, so far as I am aware, the grateris connected to the driving drum or shaft in such a manner that it isimpossible to clean it thoroughly when it is desired to change themachine from one vegetable to another. As an instance, were the graterin use on cocoa-nut, and it became necessary to change it quickly tosome other vegetable, it could not be cleaned so thoroughly as toprevent fragments of the former vegetable grated mingling with the nextvegetable operated upon. I also come niently arrange upon the same shaftwith the 'grater a revolving vegetable-cutter, the heavy disk of whichserves as a balance-wheel for the machine.

In the accompanying drawings, Figure 1 is an elevation of my machinefrom the driving side. Fig. 2 is an elevation from the revolving-cutterside. Fig. 3 is an end elevation, and Fig. the perforated grater.

Similar letters of reference indicate similar parts.

A is the frame of the machine, made of wood or iron, upon which ismounted a revolving shaft, B. Upon the driving end of this shaft iskeyed or otherwise secured a spur-pinion, G, which gears into and isdriven by the spur- Wheel D, mounted on the idler-stud 0?. Into the sideof the spur-wheel a crank-handle, E, is secured to furnish therotatorymotion 5 or the crank-handle may be replaced by a wristpin, and themachine driven by foot-power.

I F is the grater hub or cylinder, made of iron or other metal, andfirmly secured to the shaft by a key or set-screw. The periphery of thecylinder F is turned true and smooth to re ceive the grater G. Thegrater consists sirn ply of a cylinder of tin-plate perforated from theinsidein the usual manner, and constructed to closely fit the outersurface of the hub or cylinder F.

The vegetables to be operated upon are held on the table H and pressedagainst the grater. The grated vegetable is deposited in the box 'ordrawer I, situate directly under the grater,

which is on runners and can be removed when necessary.

The vegetable cutter consists of a heavy metal disk, K, firmly securedto the shaft B, and fitted with knives 7c 7r, secured in position byset-screws from the back. These knives may be set radially, as shown, orat an angle to the radius, and are arranged for ready adjustment fordifferent thicknesses of out. In front of the disk K, and above therevolving shaft B, is secured an inclined table, L, upon which areplaced the vegetables to be reduced or cut. The cuttings pass throughthe morrises-k k" in the disk K, and are deposited on the apron on,which, in turn, delivers the out tings into a tub or other convenientreceptacle placed under the machine.

A guard or cover, 0, hinged at the back and secured in position by thekey 0, prevents the grater or cutter throwing particles of vegetable offat a tangent, which, in operation, they would do were the guard Oremoved.

I11 constructing the machine for the trade, I propose to secure theboxes P P by means of thumb-nuts and bolts, and to slot the boltholes inthe boxes to one side, in order that, by loosening the thumb-nuts, theboxes can be drawn to one side, and the shaft and cutting and gratingmachinery be removed and laid away when the machine is out of use.

The grater G is driven by frictional contact; and it is essential thatthe tin cylinder be made to fit the hub F so closely as to require aslight effort to press the cylinder G off or on.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The grater G, constructed to slip freely on and off the hub F, incombination with said hub F, shaft B, pinion O, and spur-wheel D, Intestimony whereof I have hereunto set or equivalent driving mechanism,table H, my hand this 4th day of August, 1879.
